    D6R torque converter going out?

    Hello 7060. You can check your service manual on this but I believe that you should only see the 480 psi priority pressure when in priority mode, which is below 1300 rpms, and between trans. shifts, sounds like maybe you are in the priority mode all the time which can be taking oil from...

    D6R torque converter going out?

    I believe the torque converter outlet pressure spec is 60 psi. You would have to see in what condition the machines has to be in to check it. It used to be in 3rd speed stall with brakes on but I think they may have changed that, service manual would tell. maybe someone with a service...

    D6R torque converter going out?

    Hello 7060. The D6R has a priority valve system on it and I have seen them heat the torque converter when the machine stays in priority mode. The machine ECM controls the priority valve as far as when it is on or off. when it is in priority mode I believe it takes some of the oil from the...

    Caterpillar 140H transmission problem

    Hello Rafik79 I believe gears 5 6 7 8 all use a common clutch pack which if it was not engaging it would cause what you have. I can look in my book when back in office , let me know if you want me to.

    Caterpillar 140H transmission problem

    First you would see if you are getting voltage to the solenoid for that H spool. you will have to test the wires with them plugged into the solenoid. if you un-plug them from solenoid to test them the ECM will not send any voltage down the wire. If you are getting voltage then you may try...

    Cat 312BL: cant get full revs

    My book only says it is " Faster Than the high Idle Speed " it does not go into any detail as to what will cause this error. i assume it would be exactly what it is saying. the engine rpm is to high, possible the engine computer is seeing to high of engine speed, possible the speed...

    Hello digger_hunter. sounds like you got a good one alright. have you put you volt meter on the acuator motor and see if you are still getting voltage to it when you are asking it to continue to throttle up the engine. i have hooked some of the cat spoons in the wires to check them before...

    Caterpillar 140H transmission problem

    droucom they had quite a few problems with the gear shift control in the cab. it may be possible that the shift control is not telling the ecm that you are wanting voltage to the #8 coil. do you happen to have another machine there ? if so try swapping the gear shift control, and you could...

    Caterpillar 140H transmission problem

    Hello droucom, how are you checking for voltage at the solenoid wires ? are you un-plugging it and then testing for voltage. if so you cannot do that as when it is un-plugged the voltage will go away but you might see a 5 volt reference voltage coming through the wires. this is a floating...
